| Summary: | Background/Aim: This study is an attempt to quantify climate-induced increases in morbidity rates of
food poisoning cases.
Methods: Monthly food poisoning cases and average monthly meteorological data from 2004 to 2014
were obtained from the Malaysian Ministry of Health and Malaysian Meteorological Department,
respectively. Population projections in Malaysia, up to the year 2040 were adopted from the Malaysian
Department of Statistics and modified to the year 2100. The PRECIS model was used to project future
climate up to the year 2100 under the A1B scenario. Poisson generalized linear models were developed
to quantify the relationship between climatic parameters and the number of reported food poisoning
cases in the future.
Results: The findings revealed that the total number of food poisoning cases in Malaysia during the 11
years study period was 134,820 cases with 46 deaths. The mean age of the patients was 20±18 years.
Half of the cases were among the ages of 13-24 years old. Among the cases, 98.2% were Malaysians
and 55.7% were females. The PRECIS model projection under the A1B scenario showed that the surface
temperature in Malaysia has a monotonic increment for all states with slightly higher warming rates over
the Southern and Northern regions, with an increase of more than 3.0 °C towards the end of the 21st
century. Temperature gave a significant impact on the incidence of food poisoning cases in Selangor
(p<0.001), Melaka (p<0.001), and Kelantan (p<0.001). For a 1.0°C increase in temperature, the excess
risk of food poisoning in each state will increase up to 56.4%.
Conclusion: The study concludes that climate does affect the distribution of food poisoning cases in
Selangor, Melaka, and Kelantan. Food poisoning cases in other states are not directly associated with
temperature but related to long term trends and seasonality. |
